With the aim of simplifying relational database modeling, Database Modeling Step-by-Step presents the standard approach to database normalization and then adds its own approach, which is a more simplistic, intuitive way to building relational database models. Going from basics to contemporary topics, the book opens with relational data modeling and ends with BigData database modeling following a road map of the evolution in relational modeling and including brief introductions to data warehousing and BigData modeling. A break-down of the elements of a model explains what makes up a relational data model. This is followed by a comparison between standard normalization and a more simplistic intuitive approach to data modeling that a beginner can follow and understand. A brief chapter explains how to use the database programming language SQL (Structured Query Language), which reads from and writes to a relational database. SQL is fundamental to data modeling because it helps in understanding how the model is used. In addition to the relational model, the last three chapters cover important modern world topics including denormalization that leads into data warehouses and BigData database modeling. The book explains how there is not much to logical data modeling in BigData databases because as they are often schema-less, which means that BigData databases do not have schemas embedded into the database itself, they have no metadata and thus not much of a logical data model. Online bonus chapters include a case study that covers relational data modeling and are available at the author's web site: www.oracletroubleshooter.com/datamodeling.html

The Ultimate Beginner's Guide To Learning SQL - From Retrieving Data To Creating Databases! Structured Query Language or SQL (pronounced sequel by many) is the most widely used programming language used in database management and is the standard language for Relational Database Management Systems (RDBMS). SQL programming allows users to return, analyze, create, manage and delete data within a database – all within a few commands. With more industries and organizations looking to the power of data, the need for an efficient, scalable solution for data management is required. More often than not, organizations implement a Relational Database Management System in one form or another. These systems create long-term data “warehouses” that can be easily accessed to return and analyze results, such as, “Show me all of the clients from Canada that have purchased more than $20,000 in the last 3 years.” This “query,” which would have taken an extensive amount of hands-on research to complete prior to the use of database, can now be determined in seconds by executing a simple SELECT SQL statement on a database. SQL can seem daunting to those with little to zero programming knowledge and can even pose a challenge to those that have experience with other languages. Most resources jump right into the technical jargon and are not suited for someone to really grasp how SQL Actually Works. That's why we created this book. Our goal here is simple: show you exactly everything you need to know to utilize SQL in whatever capacity you may need in simple, easy to follow concepts. Our book provides Multiple Step-by-Step Examples of how to master these SQL concepts to ensure you know what you're doing and why you're doing it every step of the way. This book will allow you to successfully go from knowing absolutely nothing about SQL to being able to quickly retrieve and analyze data from multiple tables. Step-by-step we will Walk You Through the Fundamentals of Understanding How a Relational Database is Structured to how to execute Complex SELECT Statements to return large datasets from your database.

In the event of a failure - catastrophic or otherwise - immediate recovery is essential. By carefully combining multiple servers, it's even possible to hide the fact a failure occurred at all. From hardware selection to software stacks and horizontal scalability, this book will help you build a versatile PostgreSQL cluster that will survive crashes, resist data corruption, and grow smoothly with customer demand. It all begins with hardware selection for the skeleton of an efficient PostgreSQL database cluster. Then it's on to preventing downtime as well as troubleshooting some real life problems that administrators commonly face. Next, we add database monitoring to the stack, using collectd, Nagios, and Graphite. And no stack is complete without replication using multiple internal and external tools, including the newly released pglogical extension. Pacemaker or Raft consensus tools are the final piece to grant the cluster the ability to heal itself. We even round off by tackling the complex problem of data scalability. This book exploits many new features introduced in PostgreSQL 9.6 to make the database more efficient and adaptive, and most importantly, keep it running. What you will learnProtect your data with PostgreSQL replication and management tools such as Slony, Bucardo, pglogical, and WAL-EHardware planning to help your database run efficientlyPrepare for catastrophes and prevent them before they happenReduce database resource contention with connection pooling using pgpool and PgBouncerAutomate monitoring and alerts to visualize cluster activity using Nagios and collectedConstruct a robust software stack that can detect and fix outagesLearn simple PostgreSQL High Availability with Patroni, or dive into the full power of Pacemaker.Who this book is forIf you are a PostgreSQL DBA working on Linux systems who want a database that never gives up, this book is for you.

But there is so much more you can do with the language. In the SQL Cookbook, experienced SQL developer Anthony Molinaro shares his favorite SQL techniques and features. You'll learn about:Window functions, arguably the most significant enhancement to SQL in the past decade. If you're not using these, you're missing outPowerful, database-specific features such as SQL Server's PIVOT and UNPIVOT operators, Oracle's MODEL clause, and PostgreSQL's very useful GENERATE_SERIES functionPivoting rows into columns, reverse-pivoting columns into rows, using pivoting to facilitate inter-row calculations, and double-pivoting a result setBucketization, and why you should never use that term in Brooklyn.How to create histograms, summarize data into buckets, perform aggregations over a moving range of values, generate running-totals and subtotals, and other advanced, data warehousing techniquesThe technique of walking a string, which allows you to use SQL to parse through the characters, words, or delimited elements of a stringWritten in O'Reilly's popular Problem/Solution/Discussion style, the SQL Cookbook is sure to please. Anthony's credo is:'When it comes down to it, we all go to work, we all have bills to pay, and we all want to go home at a reasonable time and enjoy what's still available of our days.'The SQL Cookbook moves quickly from problem to solution, saving you time each step of the way.
